WIND-TURBINE Specification of Letters Patent.

Patented April 14, 1908.

Application filed March 11, 1907. Serial No. 361,768.

7 air currents to the wheel thereof. I

Other objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of theclaims, without de arting from the spirit of the invention.

11 the drawings forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is an elevational view of the present turbine, Fig. 2 is avertical section taken centrally thereof, Fig. 3 is a transverse sectionon the line 33 of Fig. 1,Fig. 4 is a detail view showing the arrangementof the doors.

Referring now to the drawings, the present invention comprises a baseplatform 5, upon which are mounted upwardly extending supporting legs 6,carrying a platform 7 at their upper ends. A socket-block 8 is mountedupon the base platform and has seated therein the lower end of avertical shaft 9 having a bevel gear 10 meshing with a similar gear 11carried by a horizontal shaft 12 journaled upon the base platform andarranged for connection with the operative mechanism. Uprights 13 arecarried by a bottom member 13 and have mounted thereupon a top 14 andsecured within these uprights there are a pair of upper and lowerhorizontally disposed circular bands 15. The shaft 9 is revolublyengaged through the bottom member 13 and is journaled at its upper endin a bearing block 16 mounted upon the top 14. A turbine 17 is mountedupon the shaft 9 between the bottom member 13 and top 14 and consists ofhubs 18 to which are secured a plurality of tangential verticallyextending transversely curved blades 19.

A plurality of vertical bars 20 are secured to the platform and the topat their ends and are arranged in a circular series surrounding theturbine and to each of these bars there is hinged a door 21 whichextends vertically and which is movable upon its hinges into and out ofposition to close the space between the bar to which it is hinged andthe adjacent bar at one side thereof. These doors thus extendtangentially from the circle described by the bars 20 and in a commongeneral direction. Springs 22 are arranged to hold the doors normally atthe outward limits of their movement and against the bands which limitsuch movement.

Each door 21 carries at its free side edge a pulley with which pulleysthere is engaged a chain 24, and this chain is also engaged with thepulleys 25 mounted upon the outer faces of the bars 20. Heads 20 and 20are shown as connecting the members 20. The chain 24 is engaged with avertical winding drum 26 journaled in the bottom member 13 and in thebase platform 5, this drum having a hand wheel 27 by which it may berevolved and being provided also with a ratchet detent 28.

It will be observed that the doors 21. are arranged to direct aircurrents against the blades of the turbine, and it will be seen thatwhen the drum 26 is operated to wind the chain thereupon, the doors willbe moved inwardly.

What is claimed is:

1. A mechanism of the class described comprising a base platform, aplatform mounted above said base platform, a bottom member carried bythe second named platform, uprights carried by said bottom member, a topsecured to said uprights, a revoluble vertical shaft seated at its lowerend upon the base platform and engaged through the second platform andbottom member, a turbine mounted upon the shaft above the bottom member,a plurality of current regulating doors arranged for movement toward andaway from the turbine, a flexible member connected with the doors forsimultaneous movement thereof, circular bands carried by the uprightsand arranged to limit the movement of the doors, helical spring meansarranged to hold the doors at the outward limit of their movement, and awinding drum carried by the base platform and adjacent the doors andhaving secured thereto, one end of the flexible member.

2. A mechanism of the class described comprising a base platform, aplatform mounted above said base platform, a botbars to which it ishinged and the adjacent bar at one side thereof, a chain engaged aroundthe doors and movably connected with the bars, and a winding drum, thechain being engaged with the drun In testimony whereof I afiix mysignature in presence of two witnesses.
